Estrus among us

Alex was completely stunned into silence as he stared at the two females laying beside him. The blonde one had massive boobs and freckles, but she still retained long pony ears and snout, so she still looked like Applejack in the face. The other's boobs looked just as huge, but she also still had pony facial features and wings. His mind was ablaze with worry: how would they react when they woke up and saw what had happened to themselves? And how had it happened?! Obviously, he had something to do with it, but this had never happened before with any other mares he'd been with, so was there something special about these two?

As he was still trying to work out the problem, Applejack opened her eyes and yawned. She smiled up at him, and said, "Good mornin' lover!" She looked around the room for a clock. "Whut time is it?"

Alex swallowed. "Umm...it's a quarter to six..." He leaned down. "Ho...how do you feel?" She grinned again.

"Jus' wunnerful!"

Then...she sat up.

And froze.

And...slowly...looked down at herself.

The scream startled birds from their nests as far away as the Everfree.

Pinkie sat bolt upright in her bed as her body shook, her tail twitched, her ears flop-flopped and her knees wobbled. "Woo! Something just happened, and it's a doozy!" She gradually regained control of herself and crawled out of bed. "What do you think, Gummy?" she asked her pet. Gummy stared at her, then used his tongue to first lick one eyeball, then the other. Pinkie gasped, "You're right! Something's happened to one of my friends!" As she began to bolt out the door, Gummy yawned, causing her to turn back around and stare at him in shock. "Wait...you mean two of them are in trouble?! There's not a moment to lose!" She spared a moment to scoop him up in a quick hug. "Thanks, Gummy! I don't know what I'd do without you!" then turned and rushed out of the room. Gummy watched her leave, quietly thinking.

"I just knew that Human was going to be trouble..."

Mac's "family sense" jerked him completely out of deep sleep as he sat straight up in bed that morning. As the sole remaining male of the resident Apple Family in Ponyville, it had fallen to him to be the protector of his female family members in all things, a position he took very seriously. And as far as the alien was concerned, he was no fool; he'd been aware of his older sister's feelings towards the alien from the moment she'd brought him to the Farm, and since then he'd kept a careful but unobtrusive watch on them both. He honestly had grown to like the Human...but at the end of the day, he was still an alien, and therefore not right for his sister. But, he realized, she is an adult, and he'd learned the hard way a long time ago not to interfere in the intimate side of her life, so he'd kept his feelings to himself.

But as he sat up in bed, he knew something was just...wrong.

As he left his room and made his way down to hers, he was only slightly surprised to see both Apple Bloom and Granny already there. Granny turned to him. "Where's yer sister? She ain't right...Ah kin feel it..." Apple Bloom piped up.

"Me too! She's in trouble, Mac! She might be dyin'! What're we gonna do?!"

Big Mac shook his head. "She ain't dyin', Apple Bloom. I don't wanna hear no talk like that. First, we gotta find her." He scowled. "And I don't want neither of you to worry." He walked to the window and looked in the direction of the Human's home, far, far away. "I think I know where she is..."

"Applejack! AJ! Please! Calm down!" cried Alex as he knelt next to her and held her by her shoulders, trying to console her. But there was no consoling the frightened girl. She'd flung herself awkwardly off the bed and into a corner and was now huddled in the fetal position, still screaming.

"Mah hooves! Whut happened to mah hooves?! Whut ARE these thangs?!" she screamed as she stared at her hands. She held them away from herself, closed her eyes, and let out another feral cry of utter terror.

Alex looked back over his shoulder at the other girl. "Fluttershy! Help me!!" But unlike her blonde friend, the former pony pegasus was the picture of calm.

Too calm.

She hadn't moved from her spot on the bed, from when she'd first sat up at Applejack's scream, and noticed her own changes. She'd simply stared down at herself, taking in her large breasts in their unnatural positions, held her new arms up and stared at her new hands, and then ran her hands down her legs. She felt movement behind herself and turned to look, only to discover it was her wings unfurling and spreading to their full length. She pulled the bedsheets down to look at her ass cheek, and a look of relief passed her features to see she still had her cutie mark. Only then did she seem to be aware of Alex's plea for help, so she climbed off the bed and tried to walk over to them both, holding onto the bed for support.

But that was the moment Applejack realized Alex was holding her.

She stopped screaming long enough to stare up and him and cry, "YOU! YOU DID THIS TO ME! DON'T TOUCH ME!!" then with eyes blazing and teeth clenched, went to her knees, picked him with one hand around his neck and the other gripping a thigh, and lifted him off the floor!

Alex barely had time to register he was off his feet by shouting, "Hey! What...!" before she threw him bodily across the room! Alex flew through the air, made a crash against the far wall that shook the entire house, then tumbled to the floor, covered in plaster and dislodged bricks. Applejack fell clumsily onto her face, panting, while Alex shook his head and tried to clear himself out of the debris. Meanwhile, Fluttershy had ducked just in time as the Human had been flung towards her, and was now on all fours as she crawled over to Applejack and spoke soothingly to her.

"Applejack...honey...it's alright. Don't be scared..." Applejack turned incredulous eyes up at her.

"'It's alright?!' Look at us! We're FREAKS!!" She sat back on her haunches and stared at her hands again. "Ho...how kin Ah face mah family...lookin' like...this?!" Fluttershy took both her hands in hers and spoke softly to her.

"We're not 'freaks,' my friend...we're now Humans."

The farmer's eyes grew wide as she stared at her friend, then she closed her eyes and shook her head. "This...this just ain't right! It ain't natural! Ah don't wanta be a Human...Ah'm a pony...Ah gotta change back..."

Fluttershy drew in close and gave her a hug, then held her at arm's length. "There's nothing we can do about it right now, Applejack, but I'm sure Twilight or Princess Celestia will be able to help us. In the meantime, no more screaming, okay?"

Tears started to roll down the farmer's cheeks as she looked at her friend, then she slowly nodded. Wiping her eyes, she said, "When did you git so strong?"

She smiled. "I do whatever I have to do for my friends. You know that..." Fluttershy looked back over her shoulder at Alex, then she leaned forward again and whispered in Applejack's ear. Applejack's eyes grew wide, then she shook her head. Fluttershy just looked at her. After a few moments, Applejack sighed, and nodded.

Both girls heard a groan, which caused them to turn again in the Human's direction. Applejack had the grace to blush as he slowly got to his feet, but she still remained defiant. As he held his head and swayed on his feet, she met Fluttershy's gaze for a moment, then looked away and mumbled, "Ah...Ah'm sorry if'n Ah hurt you, Alex...but Ah'm still mad at you!!"

Alex held up both hands and kept his distance. "I...damn, that stings!.. I don't blame you for blaming me...but I seriously have no idea how this happened to you two, or even if I'm the one at fault here..." Both girls' eyes grew wide.

"Who else could it be?!" cried Applejack. "You dun seen any other hunky aliens walkin' around town lately?!"

Alex hobbled over the bed and sat heavily down. He gave a weak smile. "'Hunky' aliens'. I guess that's a compliment." He shook his head to clear it. "What I mean is...I've been with Twilight, Pinkie, Rarity, and Rainbow, and none of them were affected like...this. I'm sure it has something to do with me, but maybe? Maybe there's something...different about you two?"

The mares exchanged a look, then Fluttershy said, "Different' how?" Alex shrugged.

"No idea. That's above my paygrade...more like something Twilight would be able to answer." He put a hand to the back of his head, then looked at it, relieved to see no blood. "But I think we're ignoring the elephant in the room." He stared at Applejack. "Just how are you now so bloody strong?"

"Ele-whatnow?" said Applejack. She shook her head and dismissed the remark, then looked back down at her hands in surprise. "In all the commotion, Ah dun clean fergot about that! How did Ah toss you across the dang room?!"

Fluttershy smirked. "Well, I'm no 'Twilight,' but I think we can assume your Earth pony strength has been enhanced by this change."

Alex stared at Fluttershy. "And you? Are you a "powerhouse" now, too?"

She shook her head. "No, I don't think so." She unfurled her wings and gave them an experimental flap, which sent her straight up into the air and almost through the ceiling before she put her arms up and stopped herself. As she hovered in place, she giggled, "I guess I was wrong about my strength, although it seems to be concentrated in my wings now..." She stopped flapping and landed awkwardly, trying once again to stand on two legs. After taking a few faltering steps, she managed to stand upright. "How do you do this all the time, Alex?"

"Clean living and pure thoughts," he remarked as he got up and went to his dresser. Taking out a couple of white t-shirts, he tossed them to them. "Please put these on...the sight of two hot, naked Human babes in my bedroom is starting to get me...distracted..."

Applejack exchanged a smirk with her friend as she too struggled to her feet. "Typical guy! We both bin traumatized, an all you kin see is our tits!"

Alex smirked back and held up a finger. "And your asses as well, don't forget those! But in my defense, your boobs are pretty huge, and hard not to notice!" After giving them his offerings he went and sat back down on the bed, watching them.

Applejack wobbled as she drew her shirt over her head, and tried to pull it down. Even though Rarity had made it to fit the Human's larger frame, it now just barely fit over her rack, clung to her like a second skin, and stopped just short of covering her ass. Fluttershy, however, handed hers back to him. "Unless you have some scissors or some way to make holes in the back for my wings, I can't wear this." She looked down and ran her hands over herself, hefted her Human tits, and gave them a squeeze. "Besides," she added, "I kind of like being naked in this new body..." She then took tottering steps out of the bedroom, her walking growing more confident as she went along.

"Where you goin'?" asked Applejack. Fluttershy looked over her shoulder.

"To get some wet towels for Alex to clean him up, and see if I can find some bandages for his head."

"...oh..." she replied in a small voice, as she blushed once more, then made her clumsy way over next to him and sat down. "Again, Ah'm powerful sorry Ah hurt you, Alex! Ah didn't mean it!" She awkwardly began to brush the plaster and debris out of his hair and off his shoulders, then looked back at the dent in his wall. "Ah'll pay fer the damages to yer house, just to show you how sorry Ah am..." Her giant tits brushed up against his arm as she attended to him, and despite the situation, he found himself becoming...interested. He put his hands in his lap to hide his growing erection, but it was too late.

She noticed.

"Sumthin' on yer mind?" she smiled. "Yer dick's too big to hide, yah know..." she added in a sultry voice.

He startled a bit and looked at her. "I...uh...I'm just...a little...turned on...can't help it with your boobs right on me!"

She looked down. "Oh! Were mah tits pressed up agin you?" she asked innocently, as she raised her hands behind her head and arched her back. Her eyes sparkled as she smiled up at him, leaned in closer while watching his face, and started rubbing her boobs back and forth against his arm, causing her nipples to harden and press against the fabric. "Ah'm reel sorry! Should Ah move away?"

He looked fully at her. "I'm...a bit confused. Weren't you just...ten minutes ago yelling at me not to touch you?"

Her breath was heaving and her face was flushed as she shrugged, "I figger it cain't git no worse." She then lowered her hands and scooted even closer, using one hand to grab his stubbly chin and bring his lips down to hers, and the other across his naked, now throbbing meat. "Besides," she whispered, their lips almost touching, "...sumthin' about this here new body is makin' me feel reel horny..."

As Fluttershy was loading her arms up with wet and dry towels, the unmistakable sounds of a dick going in and out of a throat reached her ears, so she hurried back to the bedroom. There, she stood in the doorway and watched as the blonde mare had fallen to her knees in front of Alex, and was shuddering and currently bobbing her head up and down between his spread legs. Fluttershy walked forward, tossed the towels onto the bed, and joined her. "Move over..." she whispered, as she knelt next to her and started caressing his inner thigh as she watched her friend, who looked like she was in absolute bliss. Her eyes were rolled back in her head as she sucked and slurped, taking him all the way into her throat and back with ease. Fluttershy fondled his balls as she whispered, "...how is it?"

Applejack shuddered again before she was able to shakily reply, "It...it tastes...wunnerful! Ah...(slurp!) Ah dun...(suuuuck!)...dun cum TWICE already jus' (sluuuurp!) ....suckin'...mmmph mmmph mmmpph...on...this...cock..."

Fluttershy smiled at her, "Well, I won't interrupt your meal..." She then looked up at Alex, who had leaned back on his elbows and was watching them both with his mouth open and his eyes half-lidded. She got to her feet and slowly climbed his chest, wrapped her arms around his neck, and passionately kissed him, then whispered in his ear, "...lie back..." Once he did, she crawled up further, spread her legs, and straddled his face, taking his head in both her hands. "Time to put that Golden Tongue to work for me, fellow Human..." Alex gladly complied and grabbed her fat ass, driving his tongue in between her hot, slick folds, which made her cry out as she bucked and gyrated her hips. "More! That's it! GODDESS, MORE!!" she screamed. "This feels so GOOD!! Keep GOING!" Alex drove his tongue into her sweet depths even deeper a few times, then drew back and suckled onto her clitoris, which drove her wild! She threw back her head and came, bucking her hips frantically as she smeared her pussy all over his hot tongue, while her tits jiggled and shook with each spasm. "No more! STOP!! I'm losing my mind!!" she screamed. But even as she said this, she pushed her cunt even harder against his face, lost in the throes of ecstasy! Thrusting her hips with each pulse, she yelled, "Don't! Stop!" So Alex smiled around his mouthful and kept sucking...until his own eyes rolled up as he himself screamed and cut loose down Applejack's throat, thrusting up and down as he pumped her full of his creamy, thick spunk over and over while she tried to swallow it all down.

Fluttershy fell over onto the bed, panting and convulsing, still experiencing shockwaves of orgasms. Alex's breath was also heaving as he wearily lifted his head and looked down at the blonde mare, who was still happily sucking the last of his cum out of his cock, then licking his balls to get all the jizz she'd let fall out of her mouth. She smiled up at him. "Mmmm...tastes mighty better than before, stud!" She planted one last loving kiss on the head of his dick and climbed up next to him, then snuggled close. "Mebbe this...Human thang won't be so bad..." she whispered, almost to herself.

Then her eyes grew wide and she stiffened in terror as she heard the sounds of a familiar hoof knock on Alex's front door.
